Subject: Re: [ubl] Namespace versioning

I agree that it would be nice if the Schema version could be identified  
separately to the namespace version, but the optionality of the W3C XML  
Schema 'schemaLocation' attribute doesn't lend itself to robust  
identification.  More importantly, what are we doing to do about  
organisations that won't accept XML instances with a 'schemaLocation' due  
to the security implications (i.e. that the 'schemaLocation' can point to  
arbitrary URL with unknown results when something is downloaded from that  

Cheers, Tony.
